Sizes not saving

Each time I launch OpenRGB I have to reset the size of my LED strip connected to my Aorus Ultra x570 bottom connector.

I have tried removing size.ors and recreating and when set and I cat the file it seems to have the correct length, but upon relaunch or cli profile selection it is gone.

In the cli I get a wrong number of colours error:

Connection attempt failed
Profile loaded successfully
Wrong number of colors specified for mode
